Chapter 1 Introduction
Product Overview
The Xycom Automation Advanced High-Integration Platform 370 (AHIP-370) board
is developed expressly for use in Xycom’s line of flat panel industrial personal com-
puters. It is based on the AHIP6 but is optimized in design, layout, and features for
use with flat panel computer systems. This integrated design approach allows Xycom
industrial PC/ATs to incorporate “Big PC” features in an extremely compact pack-
age. These “Big PC” features include AGP video PCI/ISA expansion, Celeron CPU,
full-size hard disk, status LEDs, infrared port, and integrated touchscreen.

Local Bus Interfaces
The Celeron design uses the 440BX chip set. The 440BX integrates a high perform-
ance interface from PCI to IDE. This interface is capable of accelerated data transfers.
The 440BX chipset provides an accelerated PCI-to-ISA interface that includes
•A high-performance enhanced IDE controller
•PCI and ISA master/slave interfaces
•Plug-and-play port for on-board devices
The chipset also provides many common I/O functions found in ISA-based PC sys-
tems, including:
•Seven-channel DMA controller
•Two 82C59 interrupt controllers
•8254 timer/counter
•Control logic for NMI generation
Fast IDE controller
The high-speed local bus IDE controller supports programmed I/O modes 0-4. It also
provides 4x32-bit read-ahead buffer and 4x32-bit write-post buffer support to en-
hance IDE performance.
Accelerated Graphics Port (AGP)
XGA Graphics Controller
The AGP bus controller supports CRT displays and flat panel displays with 2 MB
video memory. The controller also supports resolutions of 640x480, 800x600, and
1024x768 with 64K colors.

Note
The IDE controller supports enhanced PIO modes, which reduce the cy-
cle times for 16-bit data transfers to the hard drive. Check with your
drive manual to see if the drive you are using supports these modes. The
higher the PIO mode, the shorter the cycletime.
Select the PIO modes in the BIOS setup (refer to Chapter 3). The auto-
configure classifies the drive connected if the drive supports the auto ID
command. If you experience problems, change the PIO to standard.
On-board Memory
DRAM
The AHIP-370 has two 168-pin DIMM memory sites, providing up to 256 MB of
SDRAM (with up to 512 MB capability in the future). The memory site is populated
by 100 MHz synchronous DRAM.
Flash BIOS
The AHIP-370 board uses a Flash BIOS. Flash is used for system BIOS and video
BIOS.
Non-volatile SRAM
The AHIP-370 hardware supports non-volatile SRAM. Contact Xycom Automation
at 1-800-AT-XYCOM (1-800-289-9266) for additional information about this fea-
ture.
The SRAM comes in a module type package and contains a built-in battery and bat-
tery backup circuitry. The battery life is approximately seven years in the absence of
VCC. The SRAM supports 32Kx8 and 128Kx8 memory sizes. The RAM comes in a
32 pin dip (0.6 inches wide) standard format.
SRAM can be located at: CC000, D0000, or D8000.
DiskOnChip 2000
The DiskOnChip 2000 is a single-chip Flash disk in a standard 32-pin DIP format.
It requires an 8 Kbyte window to view as an extension BIOS. During boot up, the
DiskOnChip loads its software in the PC’s memory and installs itself as an addi-
tional drive.

Serial and Parallel Ports
PC/AT peripherals include two high-speed, RS-232, 16550-compatible serial ports
and one bi-directional Centronics-compatible parallel port:
•COM 1 of the serial ports accepts either RS-232 or RS-485 connections.
•COM 2 is RS-232 (stacked DB 25) with parallel port.
The COM2 port can be used for one of three options:
•Serial port out the 25 pin DB connector
•Touchscreen controller interface
•Infrared (IrDA) interface
The BIOS setup is used to configure the port as a serial port or IrDA port. This port
can be used as both a serial interface and an IR interface, by allowing software to
control the connection.
If the touchscreen controller is jumpered to use COM2, the 25-pin DB connector
must not be used to interface to a device. These lines are combined internally. The
BIOS setup menu for COM2 must be set to standard operation to use the touchscreen
controller on COM2.
USB
USB (Universal Serial Bus) is a "plug-and-play" interface between a computer and
add-on devices (such as audio players, joysticks, keyboards, telephones, scanners,
and printers). With USB, a new device can be added to your computer without hav-
ing to add an adapter card or even having to turn the computer off. USB supports a
data speed of 12 megabits per second. This speed will accommodate a wide range of
devices, including MPEG-2 video devices, data gloves, and digitizers.
Keyboard Interface
The keyboard interface uses a standard PS/2-style connector. A polyswitch protects
the +5 V. This device opens if the +5 V is shorted to GND. Once you remove the
shorting condition, the polyswitch allows current flow to resume.
Hard and Floppy Drives
The floppy interface supports one floppy drive. The AHIP-370 can interface to a
floppy via the on-board floppy connector or the external floppy connector.
In order to connect a floppy drive to the external connector after power up, the
floppy drive must be setup for a 1.44 MB drive and the floppy drive test must be dis-

AHIP-370 Manual

abled. If this is not done the system generates a floppy drive error during the POST
(Power On Self Test).
The enhanced IDE (EIDE) interface supports up to 2 hard drives. Hard drive inter-
face is via the Xycom plug-in backplane or the on-board IDE controller.
Caution
The higher the PIO mode, the shorter the cycletime. As the IDE cable
length increases, this reduced cycle time can lead to erratic operation.
The total IDE cable length must not exceed 18 inches. If two IDE drives
are connected, they must not be more than six inches apart.
